TracTuff PRB Rear Wheel Drive K Swap Filler Neck

$229.95

The introduction of the RWD version of the RBB/ RBC style water neck flange left a lot to be wanted; it was a slam dunk for those interested in running AN lines, but left the end-user with the headache of finding a traditional hose that would work. I've seen combinations of multiple radiator hoses joined with numerous clamps or rigid aluminium tubing that has been fabricated to navigate the engine bay; which is a great option but costly and not something everyone can do. 


With the help of Pit Garage I and am happy to announce that I now have a true solution! Just like the standard RBB Rear Wheel Drive K Swap Water Neck, this variant allows you to add coolant and bleed the system at the highest point! Originally modeled for the S2000 manifold attached to the k series head via an adapter plate and now available with slight adjustments, to fit the Skunk2 Ultra Street and Ultra Race intake manifolds with the plenum flipped. The end of the tube is VERY similar to the OEM S2000 water necks outlet position so the S2000 upper radiator hose is now a viable option for many RWD K Series swaps.

NOTE: Made to Order - Contact for ETA - If you are interested in a specific design, please email sales@tractuff.com. The outlet tube is welded so that it sits very similarly to the OEM S2000 water neck outlet does when bolted to an engine with a 15° lean to the passenger side (exhaust side). The billet neck has a 1/2" NPT port on the bottom side so you can choose to reconnect the factory water bypass hose (hose fitting option) or you can delete it (plug option), I recommend you keep it but its entirely up to you! Filler is welded so that it sits level when bolted to an engine with a 15° lean backwards (exhaust side). Depending on your fuel line routing, this may require you to make changes.
